ICRF 192
ICRF 192 is a weak DNA topoisomerase II (DNA topoisomerase II) inhibitor with an IC50 of 91 μM. ICRF 192 forms an iron-chelating derivative via ring-opening hydrolysis, which can displace Fe3+ from the Fe3+-doxorubicin complex. ICRF 192 is used for studies on the structure-activity relationship of bisdioxopiperazines and the cardiotoxicity of anthracycline drugs.

Topoisomerase II 91 μM (IC50) |
IC50 192 exhibits essentially no inhibitory activity against the growth of Chinese hamster ovary (CHO) cells, which is consistent with its weak inhibitory activity against DNA topoisomerase II[1].
ICRF 192 (concentration range; 48 h) inhibits the growth of Chinese hamster ovary (CHO) AA8 cells with an IC50 of 340 μM[3].
ICRF 192 (over a range of concentrations) inhibits the growth of mouse L cells, with an IC50 of 720 μM[3].
ICRF 192 (0-100 μM; 30 min) inhibits the catalytic decatenation activity of DNA topoisomerase II derived from human leukemia K562 cells, with an IC50 of 91 μM[3].
ICRF 192 (20-200 μM; approximately 2-3 h) enters BHK-21S cells via simple diffusion, and the intracellular concentration reaches a level close to that of the extracellular medium[2].
ICRF 192 (100 μM; 24 h) does not undergo significant metabolism in BHK-21S cells, and the radioactivity associated with cellular DNA and RNA originates from incorporation via the one-carbon metabolic pathway, rather than covalent binding of the drug[2].

Animal Model:SHR, Aoki-Okamoto strain (adult male, 200-250 g, doxorubicin-induced chronic cardiotoxicity and nephrotoxicity model)[1]
-
Dosage:50 mg/kg
-
Administration:i.p.; once weekly; 12 weeks; 30 minutes prior to doxorubicin
-
Result:Caused an average body weight decrease of 13 g in surviving rats.
Did not significantly reduce doxorubicin-induced myocardial lesions.
Among 10 evaluated animals, 1 animal had a myocardial lesion score of 2.0, 4 animals had a score of 2.5 and 5 animals had a score of 3.0.
Did not significantly reduce doxorubicin-induced renal lesions. Among 11 evaluated animals, 1 animal had a renal lesion score of 1, 4 animals had a score of 2 and 6 animals had a score of 3.
Resulted in 6 deaths among 11 animals before study completion.
